Description

Technical Field

[0001] This invention relates to an injection molding machine, and more particularly to a modular injection molding machine body. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. The injection molding machine body is an essential component of an injection molding machine.

[0003] Currently, the injection molding machine body of hydraulic injection molding machines is generally a one-piece structure. Its main body has a docking component at the front end, a motor mounting component on one side, and a distribution box mounting component on the other side. This one-piece structure has the following problems: 1) Due to serialized combinations or the length-to-diameter ratio of the barrel and screw, the length of the docking component may vary, and this one-piece structure cannot accommodate these variations, resulting in poor versatility; 2) Due to changes in motor specifications or quantity, the length of the motor mounting component may vary, but the length of this one-piece structure remains constant, limiting the installation to a fixed number of motors, further reducing versatility; 3) Changes in functional configuration may cause variations in the length of the distribution box mounting component, and this one-piece structure cannot accommodate these variations. 4) The length of the electrical box mounting components remains unchanged, resulting in poor versatility; 5) This type of integrated injection molding machine body requires lengthening of the motor mounting components and electrical box mounting components, which also lengthens the main body. However, the working stroke of the injection components of the injection molding machine is fixed. After lengthening the main body, it will result in wasted strength of the extended part and an increase in corresponding material costs; 6) The large-size injection molding machine body with this integrated structure requires a large processing area, which will increase processing costs; 7) The overall width of this type of integrated injection molding machine body will exceed the transportation requirements, thereby increasing transportation costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a modular injection molding machine body that has good versatility, low transportation cost, and can be assembled into various injection molding machines by using a small number of highly versatile modules.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a modular injection molding machine body, characterized in that: it is mainly composed of five modules assembled into one body: a main frame, a docking adjustment module, an oil tank, a motor mounting module, and a power distribution box mounting module. The docking adjustment module is detachably connected to the front end of the main frame, the oil tank is detachably disposed inside the main frame, the motor mounting module is detachably connected to one side of the main frame, and the power distribution box mounting module is detachably connected to the other side of the main frame.

[0006] The motor mounting module includes a motor mounting guard plate, which is laid flat on the lower side of one side of the main frame. The length direction of the motor mounting guard plate is consistent with the length direction of the main frame. Multiple fixing mechanisms are spaced along the length direction between the inner side of the motor mounting guard plate and the lower side of the main frame to secure them together. At least one strength-reinforcing mechanism is provided between the outer side of the motor mounting guard plate and the upper side of the main frame. During installation, the inner side of the motor mounting guard plate and the lower side of the main frame are initially positioned by the fixing mechanisms. Then, the strength-reinforcing mechanisms provide strength assurance for the outer side of the motor mounting guard plate and determine the relative position of the motor mounting guard plate and the main frame. Finally, the fixing mechanisms are used to tighten the guard plate, ensuring the strength of the inner side of the motor mounting guard plate.

[0007] The fixing mechanism includes an inner fixing plate and an outer fixing plate. The inner fixing plate is fixed to the lower part of one side of the main frame. The outer fixing plate is fixedly connected to the inner side of the motor mounting fence plate via a connecting post. The outer side of the inner fixing plate is opposite to the inner side of the outer fixing plate. The inner fixing plate is provided with at least one inner positioning groove with an upward opening. The outer fixing plate is provided with an outer positioning groove with an upward opening corresponding to the inner positioning groove. A positioning plate is inserted into the inner positioning groove and the corresponding outer positioning groove. The outer end of the positioning plate extends to the top of the motor mounting fence plate. The bottom of the inner end and the bottom of the outer end of the positioning plate are both provided with hooks. The top of the connecting post and the top of the motor mounting fence plate are both provided with hook holes corresponding to the positions of the hooks. The hooks are embedded in the corresponding hook holes to achieve the positioning of the positioning plate. The inner fixing plate and the outer fixing plate are fixedly connected by fasteners. A reinforcing rib is provided between the inner side of the inner fixing plate and the lower part of one side of the main frame. The motor mounting railing can be fixedly connected to the main frame by fastening the inner and outer fixing plates; the inner and outer positioning grooves and positioning plates can be conveniently positioned before fastening the inner and outer fixing plates, making the fastening of the inner and outer fixing plates more convenient; the hook part is embedded in the hook hole to limit the positioning plate and prevent it from easily falling out and being lost; the reinforcing rib can enhance the connection strength of the inner fixing plate.

[0008] The strength-enhancing mechanism includes an L-shaped support plate. One end of the support plate is fixedly connected to the outer side of the motor mounting guard plate, and the other end is fixedly connected to the upper part of one side of the main frame. The one side of the main frame, the motor mounting guard plate, and the support plate form a motor housing space. This strength-enhancing mechanism is simple and effectively ensures the outer strength of the motor mounting guard plate.

[0009] The aforementioned distribution box mounting module includes a mounting frame whose length direction is consistent with that of the main frame. Multiple connecting mechanisms are spaced along the length direction between the inner side of the mounting frame and the other side of the main frame. Each connecting mechanism includes a vertical support rod, a horizontal slider located on the upper part of the vertical support rod and perpendicular to it, and a horizontal slide rail cooperating with the horizontal slider. The bottom of the vertical support rod is fixedly connected to the inner bottom of the mounting frame, and the top of the vertical support rod is fixedly connected to the inner top of the mounting frame. The horizontal slide rail is fixedly connected to the upper part of the other side of the main frame. The horizontal slider slides on the horizontal slide rail to achieve the forward and backward displacement of the distribution box mounting module. The installation position of the distribution box mounting module can be appropriately adjusted by the cooperation of the horizontal slider and the horizontal slide rail. After adjustment, it is fixed with fasteners. When replacing a long distribution box mounting module, this allows for a more reasonable stress distribution on the long distribution box.

[0010] The horizontal slider is provided with at least one round through hole, and the horizontal slide rail is provided with an elongated through hole along its length. The width of the inner part of the elongated through hole along its depth is greater than the width of the outer part, so that the cross-section of the elongated through hole is stepped. A position adjusting screw is provided through the round through hole and the elongated through hole. The tail of the position adjusting screw is connected to a position adjusting nut. The position adjusting nut is confined to the inner part of the elongated through hole. Because the cross-section of the elongated through-hole is stepped, the position adjusting nut can be confined within the inner part of the elongated through-hole and will not slip out. In this way, the horizontal slider can be made to slide on the horizontal slide rail by rolling the position adjusting nut within the inner part of the elongated through-hole. During installation, first loosen the horizontal slide rail with the position adjusting screw and the position adjusting nut, and then fix the horizontal slide rail to the upper part of the other side of the main frame with fasteners. Moving the horizontal slider is equivalent to moving the mounting frame. After adjusting the relative position of the mounting frame and the main frame, fix the distribution box mounting module by tightening the position adjusting screw.

[0011] The main frame has front connecting parts on its left and right front ends. The docking adjustment module includes a docking body, and the docking body has rear connecting parts on its left and right rear ends. The front connecting parts and the corresponding rear connecting parts are positioned by stepped pins and fastened with fasteners. Using stepped pins to position the front and rear connecting parts first makes it easier to fix them; the use of stepped pins eliminates the need for machining the mating surfaces.

[0012] The main frame has multiple folded edges along its length on both sides of its top. Each folded edge has a positioning screw. The top of the main frame and the top of the fuel tank are positioned together by these positioning screws, adjusting their relative positions. Fasteners secure the front end of the main frame to the front end of the fuel tank, and the side walls of the main frame to the side walls of the fuel tank. The folded edges on both sides of the top of the main frame prevent the positioning operation from being too close to the top edge, greatly facilitating the positioning process. The positioning screws, fasteners, and the bottom of the main frame provide five-sided positioning of the fuel tank, making its fixation more reliable.

[0013] When the oil tank is detachably installed inside the main frame and extends beyond the main frame, the modular injection molding machine body is also equipped with a connecting cover. The connecting cover is supported on the top of the part of the tank that is exposed outside the main frame, and the front end of the connecting cover is seamlessly connected to the top of the rear end of the main frame.

[0014] The connecting cover is equipped with height-adjusting screws at its four corners. These screws support the connecting cover on the top of the portion of the fuel tank that protrudes outside the main frame. Adjusting the screws ensures the top of the connecting cover is flush with the top of the main frame. These height-adjusting screws not only protect the portion of the fuel tank that extends beyond its surface by connecting the cover, but also ensure the top of the connecting cover is flush with the top of the main frame, resulting in a more aesthetically pleasing overall appearance.

[0015] Compared with the prior art, the advantages of the present invention are as follows:

[0016] 1) Because the docking adjustment module is modularized and detachably connected to the front end of the main frame, only different lengths of docking adjustment modules need to be replaced due to serialized combinations or the length-to-diameter ratio of the barrel and screw, resulting in good versatility of the main frame. The width of the docking adjustment module is consistent with the installation dimensions of the main frame, and the length of the docking adjustment module can be divided into certain increments, and they can be borrowed from each other as needed.

[0017] 2) Because the motor mounting modules are modularized and detachably connected to one side of the main frame, changes in motor specifications or quantity only require replacing the motor mounting modules of different lengths, resulting in good versatility of the main frame. The motor mounting modules can be planned in series according to changes in motor specifications or quantity, ensuring a fixed number and variety, and good inherent versatility.

[0018] 3) Because the distribution box installation modules are modularized and detachably connected to the other side of the main frame, changes in functional configuration only require replacing the distribution box installation modules of different lengths, resulting in good versatility of the main frame. The distribution box installation modules can be planned in series according to changes in functional configuration, ensuring a fixed number and variety, and good versatility.

[0019] 4) The length of the main frame is designed according to the operational requirements of the injection components, ensuring sufficient working stroke. The oil tank is planned based on the number of motors. With a large number of motors, the oil tank will inevitably exceed the length of the main frame. A connecting cap solves the aesthetic problem of the oil tank exceeding the main frame's length, while also providing some protection for the excess portion. Furthermore, they are interchangeable. For example, the small-tonnage 3-speed model comes standard with one motor, while the medium-tonnage 6-speed model comes standard with two motors. Not only are the oil tank and motor mounting modules interchangeable between small-tonnage and medium-tonnage models, but when a small-tonnage model requires two motors, the medium-tonnage oil tank and motor mounting modules can also be used.

[0020] 5) The length of the main frame is designed according to the operating requirements of the injection components. It is not lengthened due to the large-sized motor mounting module and distribution box mounting module, so there is no waste or increase in material costs.

[0021] 6) The main frame, docking adjustment module, motor mounting module, power distribution box mounting module, and connecting cover are all processed separately, eliminating the need for a large processing area. Furthermore, the number of parts required for a single processing area is reduced, simplifying logistics management. Previously, the integral injection molding machine body, limited by its overall width, required milling and drilling on a large 50G or even 60G gantry machining center after the blank was welded. The modular injection molding machine body, however, only requires milling and drilling on a smaller 30G gantry machining center. Alternatively, where a large gantry machining center could only process one machine at a time, two or even three machines can now be processed simultaneously, significantly reducing processing costs.

[0022] 7) Modular injection molding machine body is extremely convenient to transport and has low transportation costs, especially for export. There is a 2x difference between standard containers and special frame boxes. With modular injection molding machine body, only some extra-wide modules need to be removed during transportation to save on transportation costs.

[0023] 8) The modular injection unit body will also shorten the design cycle when special designs are made later. In particular, once all modules are set up, it is basically just a matter of assembling the modules and then only modifying the connecting modules.

[0024] 9) This modular injection molding machine body can be universally used in different models to meet different needs, and can also be serialized into modules. Spare parts for each module can be adjusted according to market demand, and non-urgent order modules can be promptly called up to urgent orders. Urgent orders only require processing the main frame with a reduced number of parts, thus improving production efficiency. Attached Figure Description

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] The present invention proposes a modular injection molding machine body, as shown in the figure. It is composed of a certain number of highly versatile modules. It is assembled into a whole by six modules: main frame 1, docking adjustment module 2, oil tank 3, motor mounting module 4, power distribution box mounting module 5, and connecting cover 6. The docking adjustment module 2 is detachably connected to the front end of the main frame 1. The oil tank 3 is detachably set inside the main frame 1. The motor mounting module 4 is detachably connected to one side of the main frame 1. The power distribution box mounting module 5 is detachably connected to the other side of the main frame 1. When the oil tank 3 is detachably set inside the main frame 1 and extends beyond the main frame 1, the connecting cover 6 supports the top of the part of the tank 3 that is exposed outside the main frame 1. The front end of the connecting cover 6 is seamlessly connected to the top of the rear end of the main frame 1. When the oil tank 3 is detachably set inside the main frame 1 and does not extend beyond the main frame 1, the connecting cover 6 is not required.

[0040] In this embodiment, the motor mounting module 4 includes a motor mounting guardrail plate 41, which is laid flat on the lower side of one side of the main frame 1. The length direction of the motor mounting guardrail plate 41 is consistent with the length direction of the main frame 1. Multiple fixing mechanisms 42 are provided at intervals along the length direction between the inner side of the motor mounting guardrail plate 41 and the lower side of one side of the main frame 1 for fixing the two together. A strength reinforcing mechanism 43 is provided between the outer side of the motor mounting guardrail plate 41 and the upper side of one side of the main frame 1. During installation, the inner side of the motor mounting guardrail plate 41 and the lower side of one side of the main frame 1 are initially positioned by the fixing mechanism 42. Then, the strength reinforcing mechanism 43 provides strength assurance for the outer side of the motor mounting guardrail plate 41 and determines the relative position of the motor mounting guardrail plate 41 and the main frame 1. Finally, the fixing mechanism 42 is used to tighten the guardrail plate 41 to ensure the strength of the inner side of the motor mounting guardrail plate 41.

[0041] In this embodiment, the fixing mechanism 42 includes an inner fixing plate 421 and an outer fixing plate 422. The inner fixing plate 421 is fixed to the lower part of one side of the main frame 1. The outer fixing plate 422 is fixedly connected to the inner side of the motor mounting grid plate 41 through a connecting post 423. The outer side of the inner fixing plate 421 is opposite to the inner side of the outer fixing plate 422. The inner fixing plate 421 is provided with two upward-facing inner positioning grooves 424. The outer fixing plate 422 is provided with an upward-facing outer positioning groove 425 corresponding to the position of the inner positioning grooves 424. The inner positioning grooves 424 and the corresponding outer positioning grooves 425 are inserted into each other. A positioning piece 426 extends from the outer end to the top of the motor mounting fence plate 41. Both the bottom of the inner end and the bottom of the outer end of the positioning piece 426 are provided with hooks 427. The top of the connecting post 423 and the top of the motor mounting fence plate 41 are provided with hook holes 428 corresponding to the positions of the hooks 427. The hooks 427 are embedded in the corresponding hook holes 428 to position the positioning piece 426. The inner fixing piece 421 and the outer fixing piece 422 are fixedly connected by fasteners such as screws. A reinforcing rib (not shown in the figure) is provided between the inner side of the inner fixing piece 421 and the lower part of one side of the main frame 1. The motor mounting fence plate 41 and the main frame 1 can be fixedly connected by fastening the inner fixing plate 421 and the outer fixing plate 422; the inner positioning groove 424, the outer positioning groove 425, and the positioning plate 426 can be conveniently positioned before fastening the inner fixing plate 421 and the outer fixing plate 422, making it easier to fasten the inner fixing plate 421 and the outer fixing plate 422; the positioning plate 426 is limited by the hook part 427 embedded in the hook hole 428, and will not easily fall out and be lost; the connection strength of the inner fixing plate 421 can be enhanced by the reinforcing rib.

[0042] In this embodiment, the strength-enhancing mechanism 43 includes an L-shaped support plate 431. One end of the support plate 431 is fixedly connected to the outer side of the motor mounting guard plate 41, and the other end of the support plate 431 is fixedly connected to the upper part of one side of the main frame 1. One side of the main frame 1, the motor mounting guard plate 41, and the support plate 431 form a motor accommodating space. This strength-enhancing mechanism 43 has a simple structure and effectively ensures the outer strength of the motor mounting guard plate 41.

[0043] In this embodiment, the distribution box installation module 5 includes an installation frame 51. The length direction of the installation frame 51 is consistent with the length direction of the main frame 1. Multiple connecting mechanisms 52 are provided at intervals along the length direction between the inner side of the installation frame 51 and the other side of the main frame 1. The connecting mechanism 52 includes a vertical support rod 521, a horizontal slider 522 disposed on the upper part of the vertical support rod 521 and perpendicular to the vertical support rod 521, and a horizontal slide rail 523 cooperating with the horizontal slider 522. The bottom of the vertical support rod 521 is fixedly connected to the inner bottom of the installation frame 51, and the top of the vertical support rod 521 is fixedly connected to the inner top of the installation frame 51. The horizontal slide rail 523 is fixedly connected to the upper part of the other side of the main frame 1. The horizontal slider 522 slides on the horizontal slide rail 523 to realize the front and back displacement of the distribution box installation module 5. The installation position of the distribution box installation module 5 can be adjusted appropriately by the cooperation of the horizontal slider 522 and the horizontal slide rail 523. After the position is adjusted, it can be fixed by fasteners such as screws. When replacing the long distribution box installation module, the force on the long distribution box can be more reasonable.

[0044] In this embodiment, the horizontal slider 522 is provided with two round through holes (not shown in the figure), and the horizontal slide rail 523 is provided with an elongated through hole 525 along the length direction. The width of the inner part 5251 of the elongated through hole 525 along the hole depth is greater than the width of the outer part 5252, so that the cross section of the elongated through hole 525 is stepped. A position adjusting screw 526 is provided through the round through hole and the elongated through hole 525. The tail of the position adjusting screw 526 is connected to a position adjusting nut 527. The position adjusting nut 527 is limited to the inner part 5251 of the elongated through hole 525. Because the cross-section of the elongated through hole 525 is stepped, the position adjusting nut 527 can be limited within the inner part 5251 of the elongated through hole 525 and will not slip out. In this way, by using the position adjusting nut 527 to roll within the inner part 5251 of the elongated through hole 525, the horizontal slider 522 can slide on the horizontal slide rail 523. During installation, first loosen the horizontal slide rail 523 with the position adjusting screw 526 and the position adjusting nut 527, and then fix the horizontal slide rail 523 to the upper part of the other side of the main frame 1 with fasteners such as screws. Moving the horizontal slider 522 moves the mounting frame 51. After adjusting the relative position of the mounting frame 51 and the main frame 1, fix the distribution box mounting module 5 by tightening the position adjusting screw 526.

[0045] In this embodiment, the front connecting parts 11 are provided on the left and right sides of the front end of the main frame 1, and the docking adjustment module 2 includes a docking body 21. The rear connecting parts 22 are provided on the left and right sides of the rear end of the docking body 21. The front connecting parts 11 and the corresponding rear connecting parts 22 are positioned by stepped pins 23 and fastened by fasteners 24. Using stepped pins 23 to position the front connecting parts 11 and the rear connecting parts 22 first makes it easier to fix the front connecting parts 11 and the rear connecting parts 22; the use of stepped pins 23 eliminates the need for processing the mating surfaces.

[0046] In this embodiment, multiple folded edge pieces 12 are provided on both sides of the top of the main frame 1 along the length direction. Positioning screws 13 are provided on the folded edge pieces 12. The top of the main frame 1 and the top of the oil tank 3 are positioned by the positioning screws 13, adjusting the relative positions of the oil tank 3 and the main frame 1. Fasteners such as screws are used to secure the front end of the main frame 1 to the front end of the oil tank 3, and to the corresponding side walls of the main frame 1 and the side walls of the oil tank 3. The folded edge pieces 12 on both sides of the top of the main frame 1 prevent the positioning operation from being too close to the top edge of the main frame 1, greatly facilitating the positioning operation. The positioning screws 13, fasteners, and the bottom of the main frame 1 achieve five-sided positioning of the oil tank 3, making the fixation of the oil tank 3 more reliable.

[0047] In this embodiment, height adjustment screws 61 are provided at the four corners of the connecting cover 6. The connecting cover 6 is supported and connected to the top of the portion of the fuel tank 3 exposed outside the main frame 1 by the height adjustment screws 61, and the top of the connecting cover 6 is made flush with the top of the main frame 1 by adjusting the height adjustment screws 61. The height adjustment screws 61 not only serve to connect the connecting cover 6 to the top of the fuel tank 3 and protect the portion of the fuel tank 3 that extends beyond its surface, but also make the top of the connecting cover 6 flush with the top of the main frame 1, resulting in a more aesthetically pleasing overall appearance.
